Abstract

“Physical chemistry experiments” is one of the most important undergraduate chemistry experiment courses in many universities. Comprehensive as they are, these courses suffer from a drawback of lacking an experiment that connects the knowledge between different chapters and to the frontier research of the chemical society. Inspired by a published work of Prof. Dongsheng Guo’s group concerning the detection and imaging of cholinesterase using a sequentially activated diacetylene probe, we designed a physical chemistry experiment of “The photopolymerization, thermochromism and application of diacetylene vesicle”. We focused on the preparation of diacetylene vesicle, the photopolymerization of diacetylene, the thermochromism of polydiacetylene, and further explored the experiment’s potential application on the anti-forgery technology. We hope that by performing this experiment, students can have deeper understanding of different fields of physical chemistry, such as colloid, photochemistry, thermodynamics, dynamics etc., and can know more about current chemistry research on selfassembly, photopolymerization, chromogenic materials, anti-forgery, etc.

二乙炔囊泡的光聚合、热致变色及应用

“物理化学实验”是许多高校本科化学实验的重要课程之一。尽管这些课程内容全面，但它们的缺点是缺乏将不同章节之间的知识与化学社会的前沿研究联系起来的实验。受郭东生教授课题组已发表的用顺序激活的二乙炔探针检测和成像胆碱酯酶的研究成果的启发，我们设计了“二乙炔囊泡的光聚合、热致变色及应用”的物理化学实验。重点研究了二乙炔囊泡的制备、二乙炔的光聚合、聚二乙炔的热致变色，并进一步探讨了该实验在防伪技术上的潜在应用。我们希望通过这次实验，使学生对胶体、光化学、热力学、动力学等物理化学的不同领域有更深入的了解，并对自组装、光聚合、显色材料、防伪等方面的化学研究有更多的了解。

期刊介绍： University Chemistry is an educational research academic journal supervised by the Ministry of Education and co-sponsored by Peking University and the Chinese Chemical Society. It was founded in 1986 and changed to a monthly publication in January 2016. Its purpose is to promote and deepen the reform of university chemistry education and serve to improve the level of chemistry teaching in my country. The main columns are: Today's Chemistry, Teaching Research and Reform, Knowledge Introduction, Chemical Experiments, Teacher-Student Chats, Future Chemists, etc. The journal has been included in many databases such as China Journal Network Full-text Database, Wanfang Database, Taiwan Huayi Database, Chinese Science and Technology Journal Database (Full-text Edition), and American Chemical Abstracts.
